CPU Comparison
Intel Core i5-430M vs Core i7-640LM
A side-by-side comparison of specs, performance and value. The Intel Core i5-430M is an Arrandale dual-core mobile processor built on a 32nm CPU die paired with a 45nm I/O and graphics die, featuring Hyper-Threading and a first-generation Turbo Boost implementation for mainstream 2010 laptops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks on Windows 7 but struggles with modern web applications and operating systems.
Struggles immensely with modern JavaScript-heavy web pages.
Gaming
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
Integrated Ironlake graphics cannot run any modern games.
Virtualization
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
Technically supports VT-x but lacks the RAM and cores for practical use.
Efficiency
The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.
Poor by modern standards, but efficient for its time.
Specialized Performance
AI / ML
- No AI acceleration
- No AVX support
- Insufficient compute for any AI workload
- No AI capabilities whatsoever.
Content Creation
Gaming
- Graphics handled by chipset, not CPU
- GMA HD is extremely limited
- No modern API support whatsoever
- Ironlake graphics are strictly for display output and legacy 2D/low-end 3D applications.
